雅思A类小作文 making pulp and paper 流程图类

You should spend about 20 minutes on this task.

The diagram gives information about the process for making pulp and paper.

Summarise the information by selecting and reporting the main features, and make comparisons where relevant.

Write at least 150 words.

The diagram shows the process through which wood is used to manufacture pulp and paper for printing and box production purposes. Overall, it is rather sophisticated and is comprised of more than ten stages.

The process begins when trees are cut down to produce logs, after which they are chipped and combined with purchased wood chips in a digester. The resulting pulp is then washed and screened to make clean pulp.

This pulp can then be used to produce rough paper for making boxes. After forming the pulp in a former device, it is dried and formed into a reel. Next, it is cut into paper bales which are finally packed.

Alternatively, the clean pulp may be used to make refined paper for printing purposes. Once it is cleaned in pulp cleaners, it is dried and pressed, first in pulp presses and then in paper presses. Ultimately, it goes through another drying stage in paper dryers before being rolled.

The process begins when trees are cut down to produce logs, after which they are chipped and combined with purchased wood chips in a digester. The resulting pulp is then washed and screened to make clean pulp.

What happens next depends on the type of paper that needs to be produced: if it is rough paper for packaging purposes, the pulp is formed in a former device before it is dried and formed into a reel. Next, it is cut into paper bales, which are finally packed.

Alternatively, if the pulp is used to produce refined paper for printing purposes, it is cleaned further in pulp cleaners, following which it is dried and pressed, first in pulp presses and then in paper presses. Ultimately, it goes through another drying stage in paper dryers before being rolled.
